In performing a movement analysis of tasks assessment of static sitting ability with a patient that had a cerebrovascular accident, a therapist notices that the patient is leaning strongly toward their involved side (ipsilateral pusher syndrome) despite cueing to sit up tall. Although they are leaning, they are stable in this position. Using the Framework for Movement Analysis of Tasks, which movement construct does this patient have an impairment in based on this observation alone?

2. Overeating for just four weeks can increase fat mass and weight over two years later, a Swedish study shows.1 Researchers recruited 18 healthy and normal-weight people with an average age of 26. For a four-week period, participants increased calorie intake by 70% (mostly by eating fast food) and limited daily activity to a maximum of 5000 steps per day (considered sedentary). Not surprisingly, weight and body fat of the participants went up significantly during the study and then decreased after the study ended. Participants are believed to have returned to the diet and lifestyle they had before the experiment. However, two and a half years after the experiment, the mean weight gain for participants was 6.8 lbs with a standard error of 1.2 lbs.1Ernersson A., Nystrom F., and Linsstrrom T., “Long-Term Increase of Fat Mass after a Four Week Intervention with a Fast-Food Hyper-alimentation and Limitation of Physical Activity,” Nutrition & Metabolism, 2010; 7: 68.

In analyzing data from over 700 games in the National Football League, economist David Romer identified 1068 fourth-down situations in which, based on his analysis, the right call would have been to go for it and not to punt. Nonetheless, in 959 of those situations, the teams punted. Find a 90% confidence interval for the proportion of times NFL teams punt on a fourth down when, statistically speaking, they shouldn’t be punting.1 Assume the sample is reasonably representative of all such fourth down situations in the NFL.Round your answers to three decimal places. The 90% confidence interval is ______________ to ______________ .1Moskowitz, T. and Wertheim, J., Scorecasting, Crown Archetype, New York, 2011, p. 39.

A recent study13 examining the link between schizophrenia and culture interviewed 60 people who had been diagnosed with schizophrenia and who heard voices in their heads. The participants were evenly split between the US, India, and Ghana, and each was interviewed to determine whether the voices were mostly negative, mostly neutral, or mostly positive. The results are shown in Table 2.11. “Learned cultural expectations about the nature of mind and self” appear to influence how the voices are perceived. 10 pts                                       TABLE 2.11How do people with schizophrenia perceive the voices?

In 1998, NASA launched the Mars Climate Orbiter to study Mars’ atmosphere. The Orbiter traveled from Earth to Mars, before burning up in the Martian atmosphere. In an investigation, it was determined that the cause of this was that Lockheed Martin (the company that manufactured the Orbiter) used US customary units (miles, feet, inches), whereas NASA used SI units (centimeters, meters, kilometers). What characteristic of useful information was missing from this scenario?
